Abstract

The utility model discloses a sprue removing device for vehicle wheel workblanks. The sprue removing device is composed of a machine frame, an air cylinder, a guide rail, a pressure sensor, a motor, a drilling and milling cutter and the like. Four clamping jaws enable the vehicle wheel workblanks to be centered and located through the guide rail, a gear, a rack and the like. The air cylinder is lifted to enable a lifting plate, the motor, a main shaft, the drilling and milling cutter and the like to move downwards, and when the pressure sensor touches the lip end surfaces of the vehicle wheel workblanks, the drilling and milling cutter begins to rotate and continues to move downwards to drill and mill sprues. When the lower portion of a bearing plate touches a limiting column, the drilling and milling cutter will stop moving downwards. According to the sprue removing device, the process requirement that the height H from the upper end surfaces of wheel lips to the upper end surfaces of the sprues needs to be a fixed value can be met through a simple mechanical structure, the consistency of products is guaranteed, and the production efficiency is improved. The sprue removing device the advantages that the structure is simple, the process is advanced and the performance is safe and stable.
